WASHINGTON (WUSA9) -- A massive manhunt is underway for one Boston Marathon bombing suspect on Friday morning. Nineteen-year-old Dzhokhar A. Tsarnaev of Cambridge, Mass. is wanted by police after a shootout not far from Boston. The second suspect, Tamerlan Tsarnaev, was killed on Friday morning, according to officials.

In the aftermath of the shooting, Boston authorities are urging residents to stay in their homes and mass transit has been shut down or suspended, including Amtrak service between Boston and Providence. Details about the suspects are also emerging via social media.

A search of VK.com, Russia's version of Facebook, resulted in a profile page believed to belong to Dzhokhar Tsarnaev. The page contains a photo of Tsarnaev updated in March and several posts, including YouTube videos. Tsarnaev posted a YouTube Video called "Caucasian Accents" to his page, but it's unclear whether he actually filmed it.

A "quote of the day" from one of his friends is posted on the page. It reads: "We want to beat up police officers on duty, burn their cars. walking in and blow up the house of politicians, journalists, bank managers and all those who work in banks. We want to break the bones of the Nazis' assault battalions." We want to undermine all the public service" (Revolutionary Group for the Propagation of Terror, Greece).

The page also shows a link the suspect claims to have graduated from in 2011: Cambridge Rindge and Latin School. The Cambridge News Weekly and CambridgeMa.gov indicate he won a City Scholarship from Cambridge and was an all-star wrestler in hgih school.

The profile also shows "last seen at 5:04 a.m., Boston." Could he have been looking at his page on Friday morning?

As for Tamerlan Tsarnaev, we found photos of a man believed to be him boxing featured on a website. One of the captions for the photo reads: "Originally from Chechnya, but living in the United States since five years, Tamerlan says: 'I don't have a single American friend, I don't understand them.'" The captions also indicate he was a refugee via Kazakhstan, but wanted to box for US unless his homeland became independent, and he was "very religious."
